Application tiled July 10, 1908. Serial No. 442.909.

To 0 10b om if m ny eom'm'n Be it known that l. ()RVILLE 'l. \VEisER, aeitizen of the United States. residing in the eity of Philadelphia,county of Philadelphia. and State of Pennsylvania. have invented eertainlm movements in Movinglietm'e-lrojeeting tlaehines.

This invention. relating to maohines for projeetiug moving piotures, hasfor its lead ing objeet. to provide improved .means for automatieall velosing and opening the passage between the lamp and the film, thepassage be ng maintained open when the film is moved to exhibit thesubjeot and closed when the operation is oheelced or stopped.

in tho aeeompanying drawings, Figure 1 isa se -tio1ntl side elevation ofa maohine embmlving m improvements: Fig. 2 is an enlarged view of adetail of etmstruelion; Fig. 5' is a .front elevation of the lower partof the eonstruetien shown in Fig. l, and Fig. -l is a broken top view ofthe maehine.

'lhe maehine. eomprises the housing 1 having journaled therein theshaft- 2. which is revolved by the handle 3 and revolvesthe spur gears 1and 5. The gear 1 engages a revoluble pinion (i whieh is tixed to a spurgear Tougagj ng a pinion 8, the latter being fixedon a -j( mrnaledshaft. 9 whieh drives thealsual meolianism 10 for revolving the shaft.ll oarrying the lower film feeding sprooltet wheels 12. The spur gear 5drives the journaled idler gears 13, 14 and 15 throughavhieh it. isengaged with the revolublo pinion 16 fixed on the jonrnaled shaft;

17, the latter earryiug the upper film feeding sprocket; wheels 18.

d The door 19, earried by the. hinges 20 at the rear of the machine. isprovided with the lightiaperture 21, which, when the door is closed. is.in line with the machines light torture-22 wherethrough the pieture isprojeeled, from thefilm oarried by the sprockets, The door earries theguides or ,postsfitiluwmg ways 23" for the shutter 24,

the latter being adapted to move vertically inthe ways to openandolosethe passage.

from the lainp 25 through the light apertures of the. maohme. Thisshutter has thereon a log Ztleontamtng an opening Jt'i' \vherethroughextends a loop 27, whit-h, withanarm forms a lever adapted to rock onthe fulorumilf), the loop having such eur\a ture that the door can heopened and the shutter revolved without being disengaged from the lever.

The arm 28 is connected by a .tie member 30. suitably a chain, with thehub 3l' of a drum 31 whieh'is loose upon the journaled shaft 32. Fixedto this shaft is a disk 33, on the face. of whioh and Within the drum 31are the friction shoes 34 oarried by the ecrentrieally disposed arhors35. the latter being eai'ried by the disk. Springs 36, disposed betweenthe heels of the shoes 34 and the shaft, 32 with which they revolve.normally 'hold the shoes ut of frictional eons tact with the interior ofthe (lrums pe riphery. i

pinion 37 is fixed on the shaft 32 and engages a spur wheel 38 fixed tothe idler gear 12-5, so that the shaft 32 and the shoes enrried therebyare. revolved in the direction of the arrow on Fig. 2 when the maohineis operated to feed the film.

\Vhen the machine is operated at the speed requisite for exhibiting thesuhjeetof the film. the centrifugal action onus-es the shoes 3-1 tofriotionally engage the periphery of the'drnm 31 \vhieh is revolvedthereby to the extent. required for depressing the arm and elevating thearm 27. whereby the slide is raised and light permitted to pass from thelantern through the machine. "hen the operation is stopped or eheeked sothat the film is not. moved at the rate requisite for exhibition, theshoes do not engage the drum so as to'move or hold it and the shutterdrops.

llaving deserihed my invention, I elaim:

1. 1a apparatus of. the eluss described, a shutter having a straightline movement of reeiprm-ation. means wherehy said shutter revolves, andan arm adapted to oscillate, said arm and shutter being eonneotod sothat said shutter can revolve without being diS- oonneeted from saidarm. I

' Q. In apparatus of the class dosorihed. a

shutter. ways in whieh said shutter is adaptshaft, and means foreonnecting said shaft and lever, said means comprising a rentrifm galfriction device and a drum engaged by said device whereby the revolutionof said shaft efiects the movement of said lever.

4. In apparatus of the class described, a

revoluble shaft, a friction shoe, means on said shaft. \\'l'i( reby saidshoe istulmgumed so that it is caused to move outwardly-when revolved, adevice loose on said shuftand adapted to be engaged by said shoe whenrevolving, a movable shutter, and means for connecting'said device andshutter.

5.. In apparatus of the'class described a revoluble shaft, a handle forrevolving said shaft, :1 second revolnhle shaft, means eon;

neeting said shafts so that they revolve togethe'r, 1:1 julc'ruined"ffiietional shoe, means whereby said shoe is connected with saidsecondshaft, a device loose on said second shaft and ndu ited is hefriiitionall y; engaged in the presence of' the subsvribing witnesses.
